I've been trying to learn Blender and I had a whole scene created and it was working fine. I rendered out a very nice background at 7980 x 2160, but then I tried to make a video of the same scene at 1920 x 1080 and the screen is totally black. I've read through all the other posts on here that are similar and some of the posts on other forums and I cannot seem to figure this one out.

I've tried all the things mentioned in the other posts, but none of the posted fixes seems to fix my problem. Such as disabling the sequencer, or changing the film transparency setting. Here is my blender file: https://dl.dropboxusercontent.com/u/23049559/Sparks_005.blend

Some of the other posts that I tried to follow to solution this problem:

  1. Black Screen Cycles Render
  2. cycles not rendering movie clip used as background
  3. Black Screen After Rendering

This is the tutorial I was working off of: https://youtu.be/QCMyvcc3ZaU

Any ideas? I am using the cycles render.

  • $\begingroup$ There is something wrong with your download link, please update it, it is transfering as a text file. You scene is completely dark and devoid of lamps, lighting or light sources of any kind. There is probably something wrong with your material definition, the age/lifetime node combination is yielding a black material $\endgroup$ Jan 24, 2017 at 23:25
  • $\begingroup$ Right click on the link and click save link as. It will let you save the file to your local system as a blend file. I just checked the material definitions, they are good, the material is a light emitter, unless I changed something by accident. I don't remember changing anything that would cause it to turn black. I've tried everything I can think of...I'm at a loss, and I'm still new & just learning. $\endgroup$

  • $\begingroup$ Yeah, I already did, but next time use blend-exchange.giantcowfilms.com for sharing files here. Anyway your file is all black when I opened here, particles were not emitting any light, except for the original icosphere bellow the ground plane $\endgroup$ Jan 25, 2017 at 2:32
  • $\begingroup$ Ahhh copy that on the file sharing. Thanks I will do that in the future. Ok so then you have reproduced my issue. No idea what is wrong? Do you have any idea? $\endgroup$

  • $\begingroup$ Yeah, your material definition is wrong. Something about your math with particle age and life is off in your node setup, making particles emission dark. Check your node setup and check the tutorial, something must be amiss there. $\endgroup$ Jan 25, 2017 at 4:23
